TO ALL WHOM IT MAY CONCERN:

Be it known that we, JACOB C. HORTON, of the city, county, and .Stute of New York, and SAMUEL K. IIAWKINS, of Lansingburg, in the connty of Rensselaer, and State of New York, have invented a. new anduseful Improvement in Liquid and Fluid-Meters, and in the Method of Operating Valves; and we do hereby declare that the follovfinnF is a full, clear, and exact description thereof, reference being had to the accompanying dra-wings, and to the letters ot reference marked thereon'.

Our invention consists-in improvements upon :1 4 liquid and fluid-meter, and a L"newmcthod of operating vulves, described in Letters Potent granted to us, bem-ing date April 2, 1867. In the accompanying drawings- Figure 1 is c plan view ot' our improved meter, the cylinder-heads being removed, and the under parts shown by dotted lines. y

Figure 2 is a. vertical section through the centre of the mecsnringcylinders, one cylinder-head being removed. i

Figure 3 is n frontend view of thc meter.

Figure 4 is :t view of one of the valves, which operates alternately as :in induction andcduction valve, with the valve-sent, nduotionnnd edliction pipes, and cylinder-head all cast together.k

Figure 5 isc ,detached view of the bracket which connects the piston-rod Withthe reciprocating frame and l plate underneath the cylinder. V t

A A are the legs upon which the meter stands, and which mcy be cost solid with the cylinder. B B is the measuring-cylinder, made of east-iron :rnd lined with brass. C is the piston, and C the'piston-rod. B is the front hcadofthecylinder. D is n dini-caso for containing c dial-face and registering index, not shown in the drawings. E is n reciprocating frame, located underneath thc cylinder, and carried to and fro by the piston'- rod, by moans ot' the connecting bracket E attached to the front ond of thc piston-rod.' F is c skeleton plate connecting the twosidc bars of the frame E, sind having in its upper sido two grooves, g and g', shown by dotted lines in 1, but more distinctly in cross-section in fig. 3. G G- (tlic internal diameter of which is shown by dotted lines ct b, tig. 1,) is the induction pipo, branching zit-thc induction port G,a.nd running to each end of l the cylinder, where it connects with continuation cross pipes, one of which is shown at G', fig. 4. H H is the eduction pipc,l(shown by dotted lines a Z1, iig. 1,) branching at the @duction port H', 'and connecting with conf` tinnction cross pipes in the cylinder-heads, like the induction pipe, one of which said continuation cross pipes is shown at H in fig. 4. The side induction and cdn'ction pipes are cast on and with the cylinder, and thec'rossv pipes are east on and with the cylinder-heads, so that when the cylinder-heads are in place, the side and cross 'pipes unite und become continuons. At catch ond of the cylinder there 1s c conical osclllatlng vcl\c,-V, which is hollow, and has an opening or slot, V', to udinit water or other liquid or fluid into the cylinders, through induction pipo G, or ont through eduction pipe H, :is said slot coincides witn one ortho other of said pipes. S, tig. 4, is the valve-istem, and p p packing A precisely similar valve, with the some arrangement of pipes, stem, and packing, is connected with thc opposite cylindcrhead. The pistornrod moves in al stuingbox, I, fig. 3, in tlieifront cylinder-hond, but docs not pass through the rear cylinder-head. To theouter end of each valvc-stein cn crm, J,is rigidly niixed, extending downwnrthnt right angles 'with the valve-stems. These arms J are connected together at their lower cnds by :t bar, K, iig. 2, but neither the valve nor the arm J is shown :it the rear end of the cylinder in the drawing. K is c, stud iixed in the contre ofthe bur K, and projecting down into groove 7 or g, according as said stud may be thrown to thc right or left, by the means hereind after described. Z and Z are two levers piveted to thc side bars of the reciprocating frame E, (on the upper side tl1ereof,) at and i. rlhcse pivots poss through the scid side bars, under which are two transverse levers 1t` and n', attached to tho lower ends of scid pivots z' and both the upper and lower levers being attached rigidly to the pivots, which tin-n in said side bers, thus forming, in fact, bent levers, turning on Vtheir fulcro, e' and z". The

ends ot' scid transverse levers, n and et', orc connected by n spiral' spring, m, (shown clearly in iig. 2,) which tends to strain the ends of said levers towards veach other. The slots V in the vnlvesY ore on opposite sides of said valves, so that (the valves oscillating together) when the slot at the front end coincides with the induc tion pipe G, that :1t the rear end will coincide with the cducticn pipe H, and vice versa.

The operation is as follows: When the piston is moving from the rearend'to the front end ofthe cylinder, the stud K will be in the groove g of the reciprocating plate F, holding the valves in such position that the slot in the rear end valve will coincide with induction pipe G, while eduction pipe H, at-the same end, will be closed, but at the same time induction pipe G, at the front end, will be closed, and edu-ction pipe H, at the same end, will be open. The liquid (under suicent pressure) will therefore be 4forced into the rear end of the cylinder through the induction pipe and valve, moving the piston towards the front end of the cylinder, und forcing the liquid out of said front end4 through the valve and eduction pipe. When thc piston has passed to the extreme front end oi' the cylinder, the rear end of reciprocating plate F willl'have passed the stud K', which, being disengaged freni the groove g, will be suddenly thrown by the lever Z, actuated by the spiral spring Vn, across the en'd of plate F, until arrested by a ledge in line with the outer edge of groove g. This causes both valve-stems so far to oscillate as to reverse the valve ports, bringing the slot in the front vend valve to coincide with the induction pipe, and closing the eductien pipe at that end, while at the rear end the induction pipe is closedand the eduction pipe is opened 'at the'same instant. As soon as said valves are reversed Ithe pressure on the from: side of the piston will. cause it to reverse its motion automatically, and travel back towards the rear end of thecylinder, the stud K taking' the groove g, and when it reaches that point (as shown in iig. 2) the lever Z., pressing upon the stud K', will throw .it back to groove g; Aand so the reciprocating motion of the piston will be automatically kept up, and at each stokeof the piston the contents of the measuringcylinder will be discharged in uniform quantities. Thc'reciprocating frame E slides in V-shaped grooves in the legs of the machine, as shown at rr, iig. 2. 'I 'i An Aindex to be operated by familiar mechanism, which will suggest itself` to any competent mechanic,

should be attached, to indicate, on a dial-plate, the strokes Vci' the piston. The meter is intended to operate under a pressure of about two pounds to the square inch, more or' less.

Having thus fully described our invention, and its mode of operation, what we claim as new, and desire to secure by Letters Patent, i's-L v Y 1. In combination with a measuring-cylinder and reciprocating piston, the hollow oscillating valves, so constructed :is to operatealternately as induction und eduction valves," substeutially as described;
